Any of you that are in the "Mac Tech Support" biz, know that QuickBooks has been problem #1 lately. Everyone is having problems with it. It started with Snow Leopard, when not-very-old versions of QuickBooks stopped working. But they didn't simply fail to launch, they would open up and completely scramble all of your data. Then Lion came out and the same problem for even newer versions of QuickBooks. QuickBooks' "sharing" aka networking is also a disaster, with many important functions simply not available over a network. This can be a problem when you are trying to run the QuickBooks server, not on one of the regular use Macs in an office, but on the office's server.
So despite all the money I've made lately dealing with QuickBooks, I would love to start suggesting something ELSE to my clients. There must me something better out there? Something that behaves like a proper Mac program, obeying GUI guidelines. A program that isn't "programmed to fail" with each OS upgrade, so you don't have to buy a new copy of it every time you upgrade your OS. Something that supports networking/sharing. Something that can IMPORT data from QuickBooks. Something that can do all or most of what QuickBooks can do, including printing checks and all that.
I personally use a home-made web-based solution for my accounting. It works great for me, but it's definitely not polished enough for public consumption, and it's really a basic system for tracking expenses and income. I have some clients that use quickbooks basically just for that. I have others that run their entire business through quickbooks. I don't expect to get them all to change, but I really need something different to tell my clients, besides: "QuckBooks sucks, they have no tech support, their products do not function properly, and you're stuck with them, enjoy"
